The comment made by arriopolis is correct. The output registers of these compiled circuits are important for synthesizing the circuit, but not particularly interesting to measure. As you saw already, those measurements just match the truth tables they were designed to match. The QFT and measurements intended for this circuit are which gives the ...

Yes, you can in principle do any measurement as a direct physical operation. The real obstacle is to come up with a way of actually doing it in practice. The basis states of QFT-ish measurement span every qubit in the register. This means that whatever physical mechanism you are using must be merging together information as large as the register. But ...

There is one main key point in the description of your question: Is $s$ meant to be a classical secret or a quantum secret? If $s$ is meant to be a classical secret, then the answer is yes, but there is not really much quantum in the positive answer. If $s_A$, $s_B$, and $s_C$ are all $d$-state digits, then there is a simple construction that works in ...
